Description

The list of methods to do Iterator Join are organized into topic(s).

Method

String join(Iterator iterator, String s)
join

StringBuffer stringbuffer = new StringBuffer();
do {
 if (!iterator.hasNext())
 break;
 stringbuffer.append(iterator.next());
 if (iterator.hasNext())
 stringbuffer.append(s);
} while (true);
...

String join(Iterator iterator, String separator)

Joins the elements of the provided Iterator into a single String containing the provided elements.

if (separator == null) {
 separator = "";
StringBuffer buf = new StringBuffer(256); 
while (iterator.hasNext()) {
 buf.append(iterator.next());
 if (iterator.hasNext()) {
 buf.append(separator);
...

String join(Iterator iterator, String separator)
join

if (iterator == null) {
 return null;
if (!iterator.hasNext()) {
 return EMPTY;
Object first = iterator.next();
if (!iterator.hasNext()) {
...

String join(Iterator objects, String separator)
join

StringBuffer buf = new StringBuffer();
if (objects.hasNext())
 buf.append(objects.next());
while (objects.hasNext()) {
 buf.append(separator).append(objects.next());
return buf.toString();

String join(Iterator iterator, String separator)
Joins a iteratable list of objects by the given separator

if (iterator == null)
 return "";
Object first = iterator.next();
if (!iterator.hasNext())
 return first.toString();
StringBuilder buf = new StringBuilder();
if (first != null) {
 buf.append(first);
...

String join(Iterator iterator)
join

StringBuilder builder = new StringBuilder();
while (iterator.hasNext()) {
 builder.append(iterator.next());
 if (iterator.hasNext()) {
 builder.append(", ");
return builder.toString();
...

join

if (delimiter == null) {
 delimiter = EMPTY_STRING;
if (!iterator.hasNext()) {
 return EMPTY_STRING;
Object first = iterator.next();
if (!iterator.hasNext()) {
...

String join(String seperator, Iterator objects)
join

StringBuffer buf = new StringBuffer();
if (objects.hasNext())
 buf.append(objects.next());
while (objects.hasNext()) {
 buf.append(seperator).append(objects.next());
return buf.toString();
